NOAA Style Reports missing last day of each month

NOAA Style Reports missing last day of each month on the 1st of each month just after midnight, since jan 2016, fine before that
(very observant I am)

I can manually create them and they are fine, this one has me stumped, could it be they are created to fast after midnight
the files are uploaded around 00:11 to 00;15
